The Map Legend now has two more columns for Overview and Editing stat…
…us. If the layer is in overview or editing modes, the appropriate icon will appear in the layer's file entry (you may need to enable "Show file groups" in the right-click menu of the layer in the legend to see file entries).

QGIS used to do this already before the move to Qt4 - however the new QIcon idiom only seems to allow for square icons, therefore it is easier to split the results out to several columns and give them their own QIcons.

I can see room for improvement after this commit:
1. Overview and Editing icons can be also shown beside the top-level layer name, to avoid having to enable "Show file groups".
2. There also seems to be a "projection not valid" icon floating around, however this hasn't been addressed in this commit. Perhaps we need to do something for it too.
3. The column sizes have been hard-coded to arbitrary values.  I have no problem if these get tweaked further.

This commit addresses trac ticket #117.
